To all whom it may concern."

' Be it known that I, LEONARD A. YOUNG,-

a citizen of the United States of America, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Spring Construction, of which the following is a specification, reference being had therein to the accompanying drawings.

In the construction of spring seats for vehicles and the like, it is desirable to provide a base on which the springs are suitably supported and to which they may be attached securely with as little labor as possible, and it is also advantageous to provide means for securing upholstery applied to the springs, to the base.

his invention relates to spring constructions and to an arrangement thereof which affords a firm base for the springs, provides means for securing the upholstery to the base readily and combines strength and lightness with simplicity of construction whereby they may be made in large quantities at slight cost.

The invention consists in the matters hereinafter set forth and more particularly pointed out in the appended claim.

In the drawings,

Figure 1, is a View, partially broken away and partially in transverse section of a spring structure that embodies features of the invention;

Fig. 2 is a View in detail of a base. rim with adjacent parts of the structure and upholstery;

Fig. 3 is a similar view in detail showing a slight modification of the parts;

Fig. 4 is a plan view, reduced in size and with parts omitted, of the construction;

Fig. 5 is a view in detail showing one method of securing the parts without the use of a rim wire;

Fig. 6 is a view in detail showing a disposition of the parts with an outeredge rim wire; and

Fig. 7 is a further view in detail showing a base with a mar a1 ofi-set and parts applied thereto.

Referring to the drawings, a base frame is formed of flat, side and end strips 1, which may be integrally united or otherwise secured at the corner, each having a downturned outer flange 2 that is adapted to be inrolled to support a strip or sheet 3 of wood fiber, pasteboard, or other like suitable material. Where a sheet is used of the full extent of the frame, downturned spurs 4 may be struck up from the strip 1 to pierce through and be clenched up against the sheet. If, however, the'member 3 is merely a strip as indicated in Fig. 3, for tacking purposes, the other margin 25 of the strip may be inrolled and be turned to retain the member 3. If a sheet is employed that has an off-set marginal portion as indicated at 5 In Fig. 7, the base strip may merely have a depending inner flange 6 rolled against the shoulder of the off-set. Or this inner retaining flange and the corresponding spurs 4 may be omitted as indicated in Fig. 6.

Upright body springs 7 of any preferred form are suitably secured on cross members 8 of the frame, which may be flat strips with tongues 9 struck up to engage over the spring. Obviously wire supports or other like members may be used. As shown in Figs. 1, 2, 3 and {L these cross strips are secured to a rim wire 10, as by folding the ends therearound or any other suitable manner. Conveniently the inbent ends 11 may likewise grip the adjacent base coils 12 of the body springs. The rim frame may be secured to the strips 1 in a variety of ways, as for example by upturned portions 13 of the flange 2 or by separate clips 14 (Fig. 3) embracing the flange 2 and the applied wire. The body springs may be secured to cross members 15 of the frame, (Fig. 5 and Fig.

which are connected directly to the base strip 1 by folding around the latter, the rim wire-being omitted. In another form indicated in F1936 strips 16 with springs suitably clipped or secured thereto are bent at their ends around a base wire 17 and the latter is secured against the margin of the base sheet 3 by the rounded flange 18 of the frame member, the latter having an inset bend indicated at 19 to lock the wire and to closely embrace the margins of the base member 3.

In any of the constructions shown, when upholstery is applied to the springs, the apron or depending portion 20 thereof is brought under the frame and tacks 21 or like holding means driven into the strip 3 thereby holding the fabric firmly in position. The tack usually heads itself over against the frame strip thereby clenching the parts firmly together.

As a result of this construction a spring seat is obtained that has a base to which upholstery may be readily secured while the springs and supporting members thereof are readily assembled and When once in place maintain their position under all Working conditions. The sheet which closes the base or forms the tacking strip therein is so secured that it cannot Work loose while the rim of the frame is amply strong to Withstand any ordinary usage.

Obviously, changes in the details of construction may be made Without departing from the spirit of my invention and I do not care to limit myself to any particular form or arrangement of parts.

What I claim is 7 An upholstery seat construction comprising a base frame formed of end and side members, outer depending marginal flanges on said members having smoothly inrolled, lower marginal portions, a member of penetrable material secured against the under side of each frame member by the inrolled margin of the latter, cross members to the base frame, body springs thereon, upholstery carried by the body springs, a depending apron from the upholstery passed around the rounded margins of the frame members and tacking members penetrating the fabric and embedding in the members of penetrable material.

In testimony whereof I aiiix my signature in presence of two Witnesses.
